Sunday marked the 70th anniversary since the beginning of formal diplomatic relations between Australia and the Philippines which commenced on 22 May 1946.
Twitter users have been marking the celebration using the hashtag #First70Years, accompanied by photos and special memories.
The Australian Ambassador to the Philippines, Amanda Gorely, said the focus of Australia's development program in the Philippines is to support inclusive economic growth and political stability.
"Australia and the Philippines share common perspectives on many regional, economic and security issues," she told The Huffington Post Australia.
"The two countries share a common interest in cooperating in regional affairs through fora such as the East Asia Summit, Asia-Pacific Economic Cooperation and the Association of Southeast Asian Nations Regional Forum."
Gorely also noted that Filipinos remain one of the fastest growing immigrant communities in Australia, highlighting that while our formal diplomatic relations may have only started in 1946, the relationship between our nations goes back even further.
"At the 2011 Census, 225,000 Australians identified as having Filipino ancestry, up from 129,000 in 2001," she said.
"There were ties between Australia and the Philippines prior to [1946]. Some, 4,000 Australian servicemen fought alongside their Filipino brothers during WWII and Filipino pearl divers worked in Australia's fledgling pearl industry in the 1800s.
"I am always struck by the positive outlook of the Filipino people I meet from all walks of life. They have a tendency to look on the bright side."
